Answer:
A
Step-by-step explanation:
square root of 73 is about 8.5
square root of 10 is about 3. multiply by 3, you get 9.
square root of 7 is about 2.6. multiply by 5, you get 13.
when determining if you can make a triangle, if all variants of two sides can add up to be greater than the third side, you can make the triangle. so 8.5+9 > 13; 13+9 > 8.5; 13+8.5 > 9. this means it can make a triangle and all you have to do is order the sides.
8.5 is smallest which corresponds to angle c because it's opposite. 9 goes to angle a, then finally 13 goes to angle b. thus, angles c, a, b is the order.
side note: the smallest side length will always correspond with the smallest angle.
hope this helps :)
The primeter is the outside p=2+2 +3+1+1 so the primiter is 9

Let Tamara invests amount 
in 3% account. She invests 
in 2% account.
The interest after t years is given by
. After 1 year the two interests are equal, that is
Thus, Tamara has to invest 
in 3% account and 
in 2% account.
It is a geometric sequence and common ratio is <span>−<span>23</span></span><span>.</span>
